Zinc Flake Coatings
Zinc flake coatings offer a high corrosion protection system using combinations of specialised base and top coats for exacting bulk components. It is applied using the so called dip spin process.
Embraced largely by the fastener industry, zinc flake coatings are widespread and utilised within a variety of applications. Both organic and inorganic coating systems are available offering excellent protection from mechanical and chemical impact. When combined with other processes, the zinc flake system is clearly superior to comparable systems.
The baking temperatures vary from 180 – 250 celsius depending on manufacturers and products. The finishes available are completely Cr ( V1 ) free and fulfill global automotive requirements.
Zinc Alloy Plating
Zinc alloy coatings are usually deposited on ferrous substrates to enhance their bulk properties and protection from corrosion. The preferred alloy composition of zinc nickel plating is 12-15% nickel with the remainder being zinc.
Used by industry when corrosion protection is required that is superior to standard zinc plating. Zinc Nickel is the choice for high performance coatings in automotive applications and widely utilised in various applications.
EPC operate various passivation & sealing systems over zinc nickel to enhance greater barrier protection.
Traditionally electrolytically deposited zinc forms the basis ensuring sacrificial protection of the substrate material.
EPC specialise in barrel application of small components such as fasteners and pressings in meeting OEM and global specifications.
Whilst using an alkaline zinc electrolyte, this enables excellent deposit in low current areas ensuring excellent corrosion characteristics.
Enhancement of passivation & sealing systems increases barrier protection at a competitive market value.
